Objective:To develop an HPLC method for determining the total ginkgo flavonoid in self-emulsifying drug delivery sys-tem. Methods:Effective chromatographic separation was achieved using a phenomenex C18 column (250 mm × 4. 6 mm, 5 μm) with a mobile phase composed of methanol and water (0.4% phosphoric acid) with the ratio of 50 ∶50 (v/v). The mobile phase was pumped using an isocratic HPLC system at a flow rate of 1. 0 ml·min-1 , the detection wavelength was 360 nm and the column temper-ature was 30 ℃. Results:The three components in the total ginkgo flavonoid were well separated by the proposed method. The linear relationship between the peak area and the concentration was promising within the range of 2. 0-40. 0 μg·ml-1 for quercetin, 3. 0-60. 0 μg·ml-1 for kaempferide and 2. 0-40. 0 μg·ml-1 for isorhamnetin. The mean recovery of quercetin, kaempferide and isorham-netin was 98. 4%, 99. 7% and 100. 5% with RSD of 0. 92%,0. 62% and 1. 24% (n=9), respectively. Conclusion:The method is specific and stable in the determination of total ginkgo flavonoid in self-emulsifying drug delivery system.

Objective:To prepare total ginkgo flavonoid self-emulsifying drug delivery system(TGF-SMDDS)and estimate its char-acteristics in vitro. Methods:The formula of TGF-SMDDS was optimized based on the solubility tests,formula compatibility and microe-mulsion area in the pseudo ternary phase diagram. The appearance,morphology,particle size,zeta potential and in vitro dissolution of TGF-SMDDS were investigated. Results:The formula was composed of oleoyl macrogolglycerides as the oil phase,Tween-80 as the sur-factant and XCF as the co-surfactant. The ratio of oil phase,surfactant and co-surfactant was 10 ∶ 6 ∶ 4. The drug loading was 10. 0 mg· g -1 . After mixed with water,TGF-SMDDS was formed a clear and transparent microemulsion with homogeneous small spheres as seen un-der a transmission electron microscope. The particle size and zeta potential of TGF-SMDDS was(87. 4 ±26. 7)nm and( -13. 1 ±1. 5) mV,respectively. The accumulative dissolution of TGF-SMDDS in pH1. 2 hydrochloric acid solution was(96. 1 ±4. 8)% in 45 min. Con-clusion:The TGF-SMDDS can significantly enhance the dissolution of TGF in vitro,which may be a potential effective preparation for TGF.

In order to construct an integrated DNA barcoding database for identifying Chinese animal medicine, the authors and their cooperators have completed a lot of researches for identifying Chinese animal medicines using DNA barcoding technology. Sequences from GenBank have been analyzed simultaneously. Three different methods, BLAST, barcoding gap and Tree building, have been used to confirm the reliabilities of barcode records in the database. The integrated DNA barcoding database for identifying Chinese animal medicine has been constructed using three different parts: specimen, sequence and literature information. This database contained about 800 animal medicines and the adulterants and closely related species. Unknown specimens can be identified by pasting their sequence record into the window on the ID page of species identification system for traditional Chinese medicine (www. tcmbarcode. cn). The integrated DNA barcoding database for identifying Chinese animal medicine is significantly important for animal species identification, rare and endangered species conservation and sustainable utilization of animal resources.

Aim To investigate the effects of suppressor of cytokine signaling-1(SOCS-1)on advanced glycation end products(AGEs)induced-renal tubular epithelial-myofibroblast transdifferentiation and activation of JAK/STAT in cultured human renal tubular epithelial cells(HKC).Methods Stable transfections of HKC with pCR3.1 vector and pCR3.1/SOCS-1 were performed with Lipofectamine 2000,and cells were selected with geneticin.Cells were stimulated with BSA and AGEs. The protein expressions of SOCS-1,α-SMA,E-cadherin,Col I,signal transducer and activatior of transcription 1,3(STAT1,STAT3),p-STAT1 and p-STAT3 were observed by Western blot.The protein synthesis of TGF-β_1 in the supernatants of the HKC was detected by enzyme-linked immunoadsorbent assay(ELISA).α-SMA and E-cadherin mRNA were measured by reverse transcription and polymerase chain reaction(RT-PCR).Results Compared with control group,the expression levels of α-SMA protein and mRNA and Col I were significantly increased in HKC with AGEs stimulation and there was a higher concentrations of TGF-β_1 in the supernatants.However,the expression of E-cadherin protein and mRNA were decreased with AGEs stimulation.Overexpression of SOCS-1 inhibited AGEs-induced activation of STAT1 and STAT3 and high expression of α-SMA protein and mRNA and Col I,and reversed the expression of E-cadherin protein and mRNA induced by AGEs.Meanwhile,overexpression of SOCS-1 reduced the concentration of TGF-β_1 in the supernatants of HKC with AGEs stimulation.Conclusion Overexpression of SOCS-1 inhibits AGEs-induced renal tubular epithelial-myofibroblast transdifferentiation maybe partly through blocking activation of JAK/STAT.

BACKGROUND: Phenylketonuria is caused by gene mutation of phenylalanine hydroxylasel (PAH), which is mainly induced by permutation, short segments and insertion of base.OBJECTIVE: To evaluate the gene mutation of phenylalanine hydroxylasel in phenylketonuria in Hui nationality.DESIGN: Open study.SETTING: Urumqi General Hospital of Lanzhou Military Area Command of Chinese PLA; Capital Pediatrics Institute.PARTICIPANTS: A boy of Hui nationality in China and aged 3.1 years was selected in this study. The boy had intellect hysteresis in his one year and received medical treatment in his three years, while he was diagnosed as cerebral paralysis. After repeatedly inefficient treatment, he was hospitalized in our hospital on December 13, 2004. Iron sesquichloride in urine was strongly positive and concentration of serum phenylalanine was 1 680 μmol/L; therefore, he was diagnosed as the typical phenylketonuria.METHODS: 5 mL venous blood was selected from the boy and his parents, respectively, and anticoagulated with EDTA-Na2. DNA in gene group was extracted by using typical phenol/chloroform method. In addition, polymerase chain reaction (PCR) primer sequence of extron 7, 6, 11, 3, 12 and 5 of PAH gene was designed based on references. And then, PCR products were detected with 2% agarose gel electrophoresis. 5 μL PCR products were mixed with the same volume of degenerated buffer solution, degenerated at 97 ℃ for 5 minutes, put in iced bath and performed with 80 g/Lnon-degenerated polyacrylamide gel electrophoresis. After that, the products were dealt with sliver staining routinely, and single strand DNA banding patterns were analyzed and recorded. ABI377 automatic sequenator (PE Company) was used to detect PCR sequence and purify PCR product in Shanghai Boya Biotechnology Company.MAIN OUTCOME MEASURES: Iron sesquichloride in urine, concentration of serum phenylalanine and mutant gene types of phenylalanine hydroxylase.RESULTS: Extron 7, 6, 11, 3, 12 and 5 of PAH gene were analyzed in the boy and his parents. The results demonstrated that SSCP electrophoresis in extron 6 was different from that in the normal control group. Site of electrophoresis strip of his father was coincident with that of his mother, but different from that of the boy. Sequencing results indicated that point mutation (cytosine replaced by thymine), which was a R176X mutant heterozygote, occurred at the 526th site of cDNA of phenylalanine hydroxylase gene in his parents; however, two chromosomes of the boy had mutation at the same site, which was R176X mutant homozygote.CONCLUSION: Mutation of R176X homozygote of phenylketonurea is firstly reported in Hui nationality in China.

Objective To investigate the impact of diabetes on coronary artery bypass grafting (CABG)in peroperative patients. Methods Clinical data of 692 CABG patients were collected retrospectively from Sep. 2006 to Jul. 2010. The CABG patients were divided into diabetic group (n = 276) and nondiabetic group (n = 416) according to with the status of diabetes or not before operation. Blood glucose was dynamicaly monitored and treated with insulin to control blood glucose in perioperativeperiod. The postoperative effect,perioperative complication and inhospital case fatality and their relationship with diabetes were analyzed using univariate analysis. Results No significant differences were found regarding the incision complications (5. 8%vs. 4. 3 % , P > 0. 05). The volume of blood transfusion was (890. 7 ± 520. 6) ml in the diabetes group, which was not significantly different from that of (825. 2 ±518. 4)mlin the non-diabetes group (P>0. 05). No significant difference was found on cardiac arrhythmia (13.0% vs. 13. 5%),renal function insufficient (5. 1% vs. 2.4%)and case fatality (2. 9% and 1. 9%) between the diabetes and non-diabetes group (Ps >0. 05). In the diabetes group and non-diabetes group, the duration of IABP (3.7 ± 1. 6) d vs (3.5 ± 1.6)d, use of ventilator (2. 6 ± 1.9)d vs. (2. 4±1.5)d were not sigfnificantly different (Ps >0.05). The length of hospital stay and cost were (22. 0 ±8. 8)d and (8. 11 ±2. 40) thousand RMB in the diabetes group, which were significantly higher than that of (20. 6 ±7. 6)d and (7. 63 ±2. 20) thousand RMB in the non-diabeties group (t =2. 22 and 2. 71 ,Ps <0.05) . Conclusion There are no significant differences in the operative case fatality and complications between patients with diabetes and without nondiabetes. However,diabetes increases hospital stay and expense.
